摘要:

将多样化应用到网络系统、软件中以减少恶意代码传播以及单一重复攻击的多米诺效应是一个广泛的共识。提出一种基于生存能力的节点权值多样化布置算法,从节点重要性出发,将有限的差异系统布置到所有节点中。该算法能在保证单个节点对网络影响最小前提下,实现核心节点的高生存性。仿真实验表明了算法的有效性。

关键词: 多样化, 权值, 生存性

Abstract:

It is widely believed that diversity in network systems and software will decrease the virulence of malicious codes and the domino effect of singlerepeat attacks. Proposes a survivability based nodeweight diversity deploy algorithm. Starting from node importance, the algorithm assigns distinct software to all nodes. The algorithm can guarantee the minimal impact of a single node on the network systems as well as achieve high survivability of the core nodes. The algorithm is proved to be effective through simulation experiments.
